How S&P 500 ETF (SPY) Responds

US stocks lag on relative basis but often still rise in absolute terms.

Scenario Background

European equities (Euro Stoxx 50) outperforming the S&P 500 by 10%+ over 6 months is relatively rare given the decade-long US dominance since 2010. Such outperformance typically reflects either US-specific weakness (tech drawdown, recession fears) or European-specific catalysts (ECB easing, energy crisis resolution, industrial rebound).

Historical Context

European outperformance periods: 2022 (post-energy crisis recovery, value rotation), 2017 (global recovery, Eurozone stabilization), 2003-2007 (broad cyclical rally). The post-2008 period saw persistent US outperformance, driven by US tech dominance and stronger recovery. Relative valuation gaps (European P/E at 12-14x vs. US P/E at 20-22x) have been persistent but slow to close.

What to Watch For

  • EURUSD rallying above 1.15
  • Euro Stoxx 50 above its 2007 peak
  • European banks (EUFN) outperforming US banks
  • ECB monetary policy diverging from Fed
  • Value outperforming growth globally
